I get this chronic cough about 3 times a year. I get this itch in my throat, its almost as though someone poked me in the throat with a needle, right then and there I start to cough up a storm, my eyes gets watery and I start to perspire and my nose gets stuffy, most likely I will start to vomit a lot of phlegm’s. Please let me know what this is. Is it hay fever or somehting else. It doesn't feel like a cold, I dont have your other colds symptomms.
